Laser light is shown passing into a hemi-cylindrical dish filled with water. The light enters the water (at the curved side of the dish) along the normal line; no bending occurs upon entry. The light continues through the water along a straight line until it reaches the boundary with air (at the flat side of the dish). The angle of incidence in the water is just short of 48°. Since the angle of incidence is just less than the air-water critical angle of about 48.6°, there is still a little refraction in addition to the reflection.
